Abstract

A method and a system for operating bits of memory cells in a memory array, the method including applying a first operating pulse to a terminal of a first cell, the first operating pulse is intended to place the first cell into a predefined state; and applying a second operating pulse to a terminal of a second cell in the set, the second operating pulse is intended to place the second cell to the predefined state, and the pulse characteristics of the second operating pulse are a function of the response of the first cell to the first operating pulse.

Claims (10)

1. A method of operating a set of memory cells in a memory array, the method comprising:

applying a first operating pulse to a terminal of a first cell, wherein the first operating pulse is intended to place the first cell into a predefined state; and

applying a second operating pulse to a terminal of a second cell,

wherein the second operating pulse is intended to place the second cell to the predefined state, and

wherein the pulse characteristics of the second operating pulse are a function of the response of the first cell to the first operating pulse.

2. The method according to claim 1 , further comprising a step of applying a third operating pulse to a terminal of a third cell,

wherein the third operating pulse is intended to place the third cell to said predefined state, and

wherein the pulse characteristics of the third pulse are a function of the response of the first and the second cells to the first and the second operating pulses, respectively.

3. The method according to claim 1 , wherein said pulse characteristics of the second operating pulse are adjusted by adjusting the duration of the second operation pulse.

4. The method according to claim 1 , wherein said pulse characteristics of the second operation pulse are adjusted by adjusting the amplitude of said second operation pulse.
